shapely.centroid

centroid(geometry, **kwargs)

Computes the geometric center (center-of-mass) of a geometry.

For multipoints this is computed as the mean of the input coordinates. For multilinestrings the centroid is weighted by the length of each line segment. For multipolygons the centroid is weighted by the area of each polygon.

Parameters:

geometryGeometry or array_like

**kwargs

See NumPy ufunc docs for other keyword arguments.

Examples

>>> from shapely import LineString, MultiPoint, Polygon
>>> centroid(Polygon([(0, 0), (10, 0), (10, 10), (0, 10), (0, 0)]))
<POINT (5 5)>
>>> centroid(LineString([(0, 0), (2, 2), (10, 10)]))
<POINT (5 5)>
>>> centroid(MultiPoint([(0, 0), (10, 10)]))
<POINT (5 5)>
>>> centroid(Polygon())
<POINT EMPTY>
